I am seeing repeated hard system freezes on Fedora 44 that are much more common when my external HDMI monitor is attached. The machine becomes unresponsive and has to be rebooted.
Hardware:
-
Laptop: Lenovo ThinkPad X1 Extreme Gen 4i, model 20Y5000UUS

NVIDIA driver: 595.71.05
-

Display state:
-

I also see GNOME/Mutter messages such as:
gnome-shell: Cursor update failed: drmModeAtomicCommit: Invalid argument
The reboot history shows repeated sessions ending as crash. The problem is significantly more likely when this external HDMI monitor is attached.
Firmware is current according to fwupdmgr. The attached archive includes nvidia-bug-report.log.gz plus filtered journal logs, connector state, package versions, firmware update status, and crash history.
